Owl Dragon

Flying Devour 1 (As this creature enters, you may sacrifice any number of creatures. It enters with that many +1/+1 counters on it.) When Owl Dragon enters, surveil X, where X equals Owl Dragon’s power. Then draw cards equal to number of creatures devoured.{flavor}“From within the dark forest, a hoot that sounded like breaking bones and stormy winds forced us to stay out of the woods.” {-} Kayas, member of the hunter’s guild
